I like to unclip on the right, especially on roads, as I am very short and really appreciate putting my foot high on a curb!

I do think that anything goes, really, with unclipping, stopping and starting, to the point that you feel comfortable. As a mountain biker, too, though, I realize that it's important to be able to stop and start with either foot, as the terrain dictates. An example is that when you're getting going on a sidehill, you always want to mount from the uphill side....

That said, maybe it would be good to practice alternating the foot you start with. Starting doesn't have to be about the more powerful and dominant foot, it could be just about what works in that situation.

Keep riding, girl!
